CVE-2026-58927

Full vulnerability record from the local CVENow database.

Description

The vulnerability is a Use-After-Free (UAF) in the EVS AIDL HAL, arising from a data race on an unsynchronized `std::weak_ptr` within `EvsEnumerator::openCamera()`. Specifically, concurrent calls from a privileged UID (e.g., `AID_AUTOMOTIVE_EVS`) can cause a torn `weak_ptr` state, leading to a virtual call through a freed object's vtable at `cameraObj->getCameraInfo(&desc)`. This allows for potential arbitrary code execution within the `hal_evs_default` process.
